On April 1, 2021, the JSA posted on its official website that Azuma would be retiring upon completion of his last scheduled official game for the April 2021– March 2022 shogi season because he had reached the mandatory retirement age of 65 years for Free Class players. His retirement became official on May 17, 2021, after losing his 34th Ryūō tournament Group 6 preliminary round game against Yūsei Koga. He finished with a career record of 479 wins and 681 losses for a winning percentage of 0.413.
In February 2017, Azuma was one of the two JSA board members to survive a no-confidence vote taken at an emergency meeting of the JSA membership as part of the fallout from 29th Ryūō challenger controversy. The following month he was elevated to senior managing director by the JSA board at a special meeting; he served in that capacity until the end of May 2017, but decided not to submit his name as a candidate for reelection as a board member at the JSA's 68th General Meeting on May 29, 2017.
